Ion transport through polyelectrolyte multilayers under steady-state conditions

2004

Abstract The permeability of a self-assembled polyelectrolyte multilayer to small ions under the influence of an applied potential difference is studied as a function of the number of layers and the nature of the supporting electrolyte. The multilayer is described as a series of homogeneously charged membranes with alternating sign of their fixed charge. Ion transport is described on the basis of the diffusion equation and the assumption of (Donnan) electrochemical equilibrium at the boundaries between layers. The calculated steady-state current–voltage curves are found to be in good agreement with experimental linear sweep voltammograms (at low sweep rate). The permeability of polystyrenes…

Is circular economy the key to transitioning towards sustainable development? Challenges from the perspective of care ethics

2019

Abstract The Sustainable Development Goals represent a global consensus on the urgency to preserve the conditions that make life possible on this planet and ensure a future of wellbeing for humanity. Transforming consumption and production processes is a fundamental priority of this development agenda. Circular Economy has emerged as an alternative model, given its potential for value creation, while generating social and environmental positive impacts. An exploratory study carried out in Navarra (Spain) shows its potentiality for socio-economic and environmental benefits as well as technological, organizational, financial, institutional and social challenges. However, through the lenses of…

Sympathetic nervous system synchrony: An exploratory study of its relationship with the therapeutic alliance and outcome in couple therapy.

2019

In previous research, we found that sympathetic nervous system synchrony, measured via electrodermal activity (EDA), occurs between participants at the start of couple therapy. The aim now was to test whether this synchrony changes during the therapy process, and how any changes may be related to clients' and therapists' evaluations of the working alliance, and the outcome of therapy. Twelve different couple therapy processes were analyzed (24 clients, plus 10 therapists, working in pairs; hence, 4 persons per session) using EDA concordance indices and questionnaires (Outcome Rating Scale, Session Rating Scale, and Clinical Outcomes in Routine Evaluation-Outcome Measure). EDA synchrony betw…

Unisexual flowers as a robust synapomorphy in Cariceae (Cyperaceae)? Evidence for bisexual flowers in Schoenoxiphium

2012

Abstract Cariceae, the largest tribe within Cyperaceae, comprises about 2000 species in five genera. Cariceae is usually considered to be distinct from other Cyperaceae by the presence of exclusively unisexual flowers and by the arrangement of the pistillate flowers in single-flowered spikelets that are enclosed by the flask-like spikelet prophyll (utricle or perigynium). The nature of several morphological features of the Cariceae inflorescence remains controversial. The staminate reproductive units, as well as earlier reported bisexual reproductive units in Schoenoxiphium have been considered to be reduced partial inflorescences, or flowers. Aims of this study are to test both interpretat…

The bryophyte flora of Lågskär - An isolated island in the Baltic Sea

2014

This study reports the bryophyte flora of Lågskär, an isolated lighthouse island in the Åland province of Finland. A total of 81 bryophyte species were found on Lågskär, including 74 moss species and seven liverwort species. Syntrichia ruraliformis is reported for the first time in Finland, whereas Ceratodon conicus was believed to be extinct in Finland and Brachythecium turgidum was considered regionally extinct from southern Finland. peerReviewed

STUDI TASSONOMICI SU ADENOSTYLES ALPINA (ASTERACEAE) IN ITALIA MERIDIONALE

Adenostyles Cass., è un genere endemico europeo, appartenente alla la tribù delle Senecioneae, e fa parte del cosidetto ‘gruppo Quadridentato’ insieme ai generi Caucasalia B. Nord., Dolichorrhiza (Pojark.) Galushko, Iranecio B. Nord. e Pojarkovia Askerova. Esso è prevalentemente distribuito in tutto il territorio alpino, ma il suo areale si estende anche alla Spagna settentrionale, Corsica (Francia) e lungo tutta la catena appenninica in Italia, comprese le montagne della Calabria e della Sicilia, Balcani e, dubitativamente, in Grecia. Nel presente studio vengono presentati i risultati sugli studi tassonomici effettuati sui taxa appartenenti al gruppo di Adenostyles alpina (Asteraceae) pres…

Effect of exercise on gut microbiota and metabolic status modulation in an in vivo model of early obesity and NAFLD

2018

1 p. Childhood obesity is one of the most serious public health concerns from this century, associated with metabolic syndrome, nonalcoholic fatty liver disease (NAFLD) and gut microbiota alterations. Physical exercise improves obesity and NAFLD progression, modulating the gut microbial balance. We aim to investigate the effect of physical exercise on gut microbiota and the metabolic status of an in vivo model of early obesity, metabolic syndrome, and NAFLD.

Jēkaba Esera herbārijs

2021

Latvijas Universitātes Botānikas un mikoloģijas kolekcijās glabājas vairākas vēsturiskās herbāriju kolekcijas, ko veidojuši dabaspētnieki vai to organizācijas. Viena no šādām kolekcijām ir agronoma Jēkaba Esera (Essers, citkārt Ezers; 1864 -1927) herbārijs, ko tās īpašnieks savā testamentā novēlēja Latvijas Universitātei. Esera herbāriju veido piecas biezas mapes, kuras satur 1186 Sāmsalā Igaunijā ievākti augu paraugi, starp kuriem sastopami arī dabas retumi.
